-173 BROWN FKM 75D O-RING

APG stocks the VB75173, an AS568-173 brown Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 8.487 in (215.57 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 8.693 in (220.8 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against aggressive chemicals, engine and transmission fluids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for long service life in hot, chemically aggressive environments and outstanding high-temperature capability. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in ketones and esters or amines.

It sees regular use in chemical processing, automotive fuel systems, and aerospace.

VB75173 ships individually. Unit weight is approximately 0.0167 lb and nominal inside diameter is listed as 8 1/2 inch.
